throwing a ball on the object
why is it 'easier' to rotate the object
when acting on the point farther away
from the point of rotation
(with greater r) ?
i know it is connected with angular momentum and so on
but why is it so?
it seems to me that it must be because of the way
force/acceleration/momentum/whatever the best
is 'distributed' between the
points/particles/atoms/??
of the object but i cant
think of any good way to touch this subject.
could anyone help?

this lecture states the same in a different way but gives no reason.
you cant use A to prove A
this lecture assumes that you will mulitply by r but gives no reason why
sure the numbers are correct but that's hardly a reason.
as far as i can see to give a reson one would have
to describe forces (or whatever good word) acting
on and within the bolt.
